Grow your garden plants safely with this compact GardenKraft 3-Section Grow Tunnel Greenhouse. Designed to give plants in each section plenty of space while remaining compact, this greenhouse is great for patios, balconies, and small gardens. The tunnel consists of an easily-assembled frame, made from powder-coated steel tubes, which are joined together by solid plastic connectors. Also, the plastic cover is then tied to this frame and secured using the ground pegs to ensure everything stays in place. For durable use, the tunnel's plastic cover consists of two layers of polyethene (PE) with an internal grid sandwiched in between. Plus, this gives it a perfect balance between transparency and lightweight, while being strong and thick enough to keep out bad weather or pests.
